Is there a bug in this?  I can not get best bet results regardless of the query string.  For example, the following (according to MSDN documentation) should process the query rules and return a best bet.  But it doesnt.  Am I doing something wrong in the query?  It only seems to return ordinary results.  Performing the same search via Sharepoint's UI returns the best bet at the top.

$.ajax({
        url: "http://myserver/sites/mysite/_api/search/query/?processbestbets=true&enablequeryrules=true&querytext='" + searchText + "'",
        type: 'GET',
        headers: {
                   "accept": "application/json; odata=verbose"
               },
        success: myCallback,
        error: function(data) {
            alert(data.responseXML.text);
        }
    });

I wonder if it has anything to do with the fact that we are running 2013 in the 2010 UI mode.  The API itself works for ordinary results, it just wont return anything for best bets.  Do you know if that might be the reason?  Using a 2013 system (using the 2013 UI), we do get best bets coming up.
